XL-XR 600

Recommended Posts

XL, XR, interchangeability of engine parts. I have a 1986 XR 600 bottom end and jug, bored to 101mm. A 1995 XR 600 cylinder head, hot cams stage 1 camshaft, and I'm trying to fit a 1983 XL cylinder head cover. So far I know that the rockers are not the same as the '95, is there anything else I should know before I spend anymore money on this project? Is the casting the same for the valve covers, part numbers aren't showing me much... Any help would be amazing!

No dice.... 83 is a dual carb bike, different head, head cover and so on. Also, the 83 xl has a reed valve in the head to cool the secondary side intake valve. This means that it even has a different head and head cover gasket than other dual carb bikes.

There are lots of threads on the interchangability of parts on these bikes if you search.
